Researchers reviewed existing studies about adding spirulina, a type of blue-green algae, to foods. They wanted to see what nutrients it contains and how it might affect health when eaten in food products. The review looked at many different areas including nutrition, health effects, and how well people like foods with spirulina added.
The review found that spirulina is rich in protein, healthy fats, vitamins, and minerals. Early research suggests it might help reduce inflammation and oxidative stress in the body, improve blood sugar control, and support healthy cholesterol levels. Spirulina also contains special compounds that act as antioxidants. The algae grows with little land and water, making it environmentally friendly.
However, it's important to know this evidence comes mostly from early laboratory and animal studies, with only limited research in humans. The review also noted that spirulina can sometimes be contaminated with heavy metals during production. Since this is a review of existing research rather than new human trials, we can't say for sure how spirulina in foods affects people's health.
Readers should understand that while spirulina shows promise as a nutritious food ingredient, more human research is needed to confirm any health benefits. The findings provide guidance for food companies interested in using spirulina, but don't yet offer clear health recommendations for individuals.
